I'm getting one for Xmas but I have used a friend's and the Sony reader is excellent. There is no way that I would go back to paper books unless they were reference books but Google seems to fill that void. The battery lasts for yonks (6 readings of War & Peace I am led to believe)and if you add a memory card/stick, you can store thousands of books. It has a page mark facility and you can magnify the print. The print is incredibly easy to read. As far as I am concerned the paper book is dead.
